Built on the first proprietary Chinese wiki software enabled by extensive Web 2.0 elements, baike.com grows to be the largest “Chinese Wikipedia” with improving quality where the content is updating continuously through collective human knowledge contribution.

As the first commercial wiki application in China, baike.com also makes huge contribution to the community and society by promoting mutual trust and social collaboration.
